Space.bar.not.working-help!

Hi,

 

One.day.I.went.to.turn.on.my.computer.and.it.started.beeping...It.doesn't.stop.until.you.press.a.key.on.the

keyboard.and.then.the.screen.says."Hardware.profile/configuration.recovery.menu."..Profile.One.is.the.

only.profile.you.can.choose.so.I.press.enter.and.it.starts.normally.but.the.only.thing.that.doesn't.work.is.

the.space.bar.

 

Any.suggestions.on.how.to.fix.this?

 

Thanks,

 

Christina
